It is for this reason that PCB123 employs a variety of global display settings. Beginners tend to be adversely affected more than experienced users but everyone has a different threshold of overload and fatigue and not everyone agrees on the best way to reduce it. This can have a negative effect on productivity and can be a major contributor to mental fatigue. These designs can lead to the subjective phenomenon of information overload. This becomes especially important on very dense designs or designs that have a complex topology. The point is that what works for some people, does not always work for others. Some schemes are quite creative and pleasing to the eye while others seem to offend the senses. One of the interesting things that PCB123 technical support notices when processing orders is the incredible diversity of color schemes and display settings that different users prefer.
